The maximum thoracic spinal ROM during flexion and extension was measured using inclinometers, with the optoelectronic motion capture system (Vicon) serving as the control group.ResultThe thoracic spinal ROM during flexion was 14.5 ± 10.5°; during extension was 19.0 ± 9.2°, and the total ROM was 33.5 ± 14.0°. The inclinometers showed moderate to high correlations with the Vicon results, particularly in measuring flexion ROM, which exhibited the highest effectiveness (r = 0.84∼0.89). The accuracy of the inclinometers was enhanced by ensuring a cervical nodding and fixation position. Additionally, it was observed that females were more suitable candidates for thoracic spinal ROM measurement using inclinometers, as they exhibited higher correlations with the Vicon results.ConclusionThis study successfully validated the accuracy of the inclinometer as a convenient thoracic spinal ROM measurement method, that can save significant time for physiotherapists in clinical settings. The measurements obtained in this study may serve as a preliminary reference for the thoracic spinal ROM in healthy individuals and standardized protocols for using the baseline bubble inclinometer.</p>","PeriodicalId":15129,"journal":{"name":"Journal of Back and Musculoskeletal Rehabilitation","volume":" ","pages":"10538127251357101"},"PeriodicalIF":1.4,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144690379","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both groups completed a six-week rehabilitation program with two sessions per week, followed by a six-week therapy-free period. Trunk range of motion, mobility-dependent pain, and perceived health were analyzed as predictors of QOL using correlation and linear regression.ResultsIncreased trunk mobility and elevated perceived health are positively associated with QOL in individuals with NSCLBP.
